OK I am a mod here and am having log in issues as well. It seems to be worse with Internet Explorer in fact on multiple attempts I have only got in once.

But Google Chrome works for me with one glitch. I hit my bookmark link which takes me to RCU but shows that I am not logged in. I hit the log in button and this takes me to my profile WITHOUT ANY USER ID OR PASSWORD ENTRY after this I can got to any forum.

So if you are having problems try Chrome and see what happens.

BTW got my super powers back so be afraid, be very afraid.
